Trypanosoma brucei gambiense infection in vervet monkeys: a potential model for early-stage disease.

Background: Non-human primates are important experimental models for human African trypanosomiasis.

Methods: Six monkeys were intravenously inoculated with 10(5) trypanosomes of Trypanosoma brucei gambiense IL 3253. They were monitored for 180 days for parasitemia, hematology, clinical and biochemical profiles.

Palpable discrete breast masses in young women: two of the components of the modified triple test may be adequate.

Background: Palpable breast masses in young women, though usually benign, are a common source of anxiety. Current practice is assessment using the modified triple test (MTT). This entails clinical breast examination (CBE), ultrasound scans and cytological examination of a fine-needle aspiration biopsy specimen (FNAC).

Prevalence and types of coinfections in sleeping sickness patients in kenya (2000/2009).

The occurrence of coinfections in human African trypanosomiasis (HAT) patients was investigated using a retrospective data of hospital records at the National Sleeping Sickness Referral Hospital in Alupe, Kenya. A total of 31 patients, 19 males and 12 females, were diagnosed with HAT between the years 2000 and 2009. The observed co-infections included malaria (100%), helminthosis (64.

Efficacy of the novel diamidine compound 2,5-Bis(4-amidinophenyl)- furan-bis-O-Methlylamidoxime (Pafuramidine, DB289) against Trypanosoma brucei rhodesiense infection in vervet monkeys after oral administration.

Owing to the lack of oral drugs for human African trypanosomiasis, patients have to be hospitalized for 10 to 30 days to facilitate treatment with parenterally administered medicines. The efficacy of a novel orally administered prodrug, 2,5-bis(4-amidinophenyl)-furan-bis-O-methlylamidoxime (pafuramidine, DB289), was tested in the vervet monkey (Chlorocebus [Cercopithecus] aethiops) model of sleeping sickness. Five groups of three animals each were infected intravenously with 10(4) Trypanosoma brucei rhodesiense KETRI 2537 cells.

Biochemical changes in cerebrospinal fluid of Chlorocebus aethiops naturally infected with zoonotic Meningonema peruzzii.

Background: Thirty-four wild Chlorocebus aethiops monkeys were trapped for research purposes.

Methods: During routine quarantine check-up, cerebrospinal fluid (CSF) and blood were microscopically examined for parasites. Estimations of CSF protein levels were made by the biuret method and the white cell counts by the hemocytometer.
